Overview
La carte Click Board™ CAN Isolator permet une communication CAN isolée. Elle transporte l'émetteur-récepteur CAN ADM3053 à signal et alimentation isolés avec un convertisseur CC-CC isolé intégré.
Le CAN Isolator Click Board™ est conçu pour fonctionner sur une alimentation 3,3 V ou 5 V. Le CAN Isolator Click Board™ communique avec le microcontrôleur cible via l'interface UART.
The CAN Isolator Click Board™ provides isolated CAN communication. It carries the ADM3053 signal and power isolated CAN transceiver with an integrated isolated DC-to-DC converter, from Analog Devices. The click is designed to run on either 3.3V or 5V power supply. The CAN Isolator Click Board™ communicates with the target microcontroller over UART interface.
The CAN Isolator Click Board™ carries a DB 9-pin male connector.
ADM3053 FEATURES
The ADM3053 is an isolated controller area network (CAN) physical layer transceiver with an integrated isolated DC-to-DC converter.
The ADM3053 creates a fully isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates of up to 1 Mbps.
CONNECTOR FEATURES
This is a standard DB 9-pin male connector.
